Vitamin D is a fat soluble vitamin that is responsible for fostering the absorption of calcium, magnesium and phosphate in the body.
The synthesis of calciferol is dependent on the availability of a related steroid called cholecalciferol (vitamin D3), which may be synthesized in the skin or absorbed from the diet because keratinocytes of the epidermis and fibroblasts of the skin is response for producing vitamin D3(calciferol) by absorbing it from ultraviolet light when during exposure to UV B photons which protolyses provitamin D3 to pre vitamin D3 in the human body.
It can also be gotten from food sources like milk, cheese, cereals, liver,meat e.t.c.

The answer to this question would be: start doing CPR.
If the victim becomes unresponsive, probably the foreign body completely obstructs the airway and the oxygen level is already too low. Without the victim help, taking out the foreign body will be hard.
In this case, CPR will be the best option since the pressure from chest might push the foreign body away and the CPR can help circulate the blood.
